The report states Chance choked on a diaper wipe after his father beat him.

All this comes as the agency charged with protecting children admits a mistake was made.

"There is no question we had system failures that we have to get better at. There's no question," said Mike Carroll, DCF secretary.

"When the newborn baby Chance was born, he was born on July 27th, we did receive a call on the hotline on July 28th, from a woman who wanted be anonymous," Carroll said.

Records obtained by NBC2 show that woman called to report Chance's mom was a "opiate user" and expressed concern about Chance's well-being.

"It was determined by that hotline councilor that, uh, she just believed most of it was hearsay," Carroll said.

Speaking Thursday in front of the Senate Committee on Children and Families, Carroll admitted the called was "screened out," meaning the DCF worker didn't see a reason to follow up.

"We have been in the process of trying to review why that call wasn't accepted. We know it should've been."

Carroll admitted he's since listened to that call, and determined it met all the qualifications for a credible tip.

"In the end I have one person, who's listening to a call, and has to make a judgment call ... and in this case that judgment turned out not to be correct."

In a statement sent to NBC2, Carroll said his agency has started an internal review of the case. He did not put a timeline on when that review will be completed.

"It certainly met the metrics and should have resulted in a call where somebody went to the hospital to check."

Walsh and Bury are both in the Sarasota County Jail on a first-degree murder charge.

Governor Rick Scott, visiting Punta Gorda on Thursday for a jobs announcement, said the story of Baby Chance has captured the state's attention, and as a parent, he takes it personally.

He said he is fully aware of possible issues with DCF, but he has faith in Carroll.

"I have two daughters, four grandchildren. You can't imagine losing one of them. First thing you think about is, how can anything like this happen to anybody? What you know is that Secretary Carroll is very focused. We've added child protective investigators, we have rapid response teams, he's going to figure it out and constantly improve," Scott said.
